DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elastic warp knitted fabric and a method for producing the same, and more particularly to an elastic warp knitted fabric having a woven appearance and a method for producing the same.

[0002]

2. Description of the Related Art Ordinary plain elastic knitted fabrics generally have a satin structure, in which sinker loops floating on the sinker side, that is, on the front side as a knitted fabric, are arranged in a right-up and down-right shape. It has a so-called warp knit satin appearance, and is not fresh because of familiarity.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elastic warp knitted fabric having a woven appearance and giving a fresh impression while being a knitted fabric, and a method for producing the same.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an elastic warp knitted fabric, which comprises one of a satin loop of a sinker loop group rising to the right and a satin loop of a sinker loop group falling to the right made of inelastic yarn having a satin texture. But the inelastic yarn
Swing in the same direction as the swing direction of the
Also swung not been pressed by the elastic yarn sinking inside the knitted fabric, the other sinker loop group satin th non bullets
Swinged in the opposite direction of the sinker loop of the yarn
It is an object of the present invention to provide an elastic warp knitted fabric comprising a satin structure embossed on the surface by an elastic yarn, and a method for producing the same.

The elastic warp knitted fabric of the present invention has a satin appearance, but usually has a satin loop of a sinker loop group in only one direction (hereinafter referred to as "sinker loop"). Has a weft effect different from that of warp knit satin and has a woven appearance. The satin organization may be any of three-course repeat, four-course repeat, and six-course repeat.

As the elastic yarn used in the elastic warp knitted fabric of the present invention, a rubber yarn, a spandex yarn, a bare yarn such as a polyetherester fiber, or a core spun yarn or a covering yarn using a sheath yarn of cotton or the like. Can be mentioned. In order to obtain a glossy and clear appearance, a transparent type bare yarn is desirable, and among these, a bare fiber of a polyetherester fiber is desirable. As the thickness of the elastic thread,
10 to 1,000 denier is preferable, and practically 10 to 5 denier.
60 denier is common.

In the elastic warp knitted fabric of the present invention, the warp effect is exhibited by further arranging the elastic yarns in the warp direction, and the fabric-like appearance can be further improved. As a method of arranging in the warp direction, there is a normal warp insertion method of an elastic thread. That is, 00/22 or 00 for each wale.
What is necessary is to insert while shaking to / 22/00.

[0008] As the non-elastic yarn, filaments such as nylon, polyester, rayon, acetate, and silk have a glossy and beautiful appearance.
Natural fibers such as spun yarn or cotton of these materials may be used. The thickness of these yarns is preferably 10 to 200 denier as total denier.
20-100 denier is common.

[0009] Such an elastic warp knitted fabric is used as a waving thread so that either one of a sinker loop rising to the right and a sinker loop falling to the right made of a non-elastic yarn having a satin texture is not raised on the surface of the knitted fabric. It can be manufactured by inserting the elastic yarn to be used and interlacing so as to sink into the knitted fabric.

A draft yarn is used as an elastic yarn which is a waving yarn. The method of inserting the elastic yarn is as follows.
In the same course, if the elastic yarn is swung in the direction opposite to the swing direction of the inelastic yarn sinker loop, the inelastic yarn sinker loop will be lifted, while in the same course, the elastic yarn must be swung in the same direction or neither. The sinker loop of the inelastic thread sinks.

The knitting machine used in the present invention includes:
Raschel knitting machines, in which elastic yarns are easily inserted, are generally used. The minimum number of reeds is two, that is, one for inelastic yarn and one for elastic yarn. In order to express the warp effect and simultaneously positively obtain the elasticity in the two directions of warp, it is desirable to use one sheet for the warp direction and one sheet for the weft direction in total for elastic yarn.

Knitting machine gauge: 9 to 36G (number of stitches / inch)
The range is preferably 14 to 28 G in practical use.

The elastic warp knitted fabric of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing one embodiment of the present invention,
It is the figure seen from the sinker side, ie, the front side of the knitted fabric. In FIG. 1, a sinker loop 1 descending to the right is lifted up by an elastic yarn 3 and a series 5 thereof constitutes a weft adjusting effect. The sinker loop 2 rising to the right is sunk into the knitted fabric by the elastic yarn 3 and is hidden and does not appear on the surface. On the other hand, the series 6 of the needle loop and the warp-inserted elastic yarn constitutes a warp adjusting effect, and 5 and 6 give a woven appearance.

[0014]

In a normal elastic warp knitted fabric, the surface of the knitted fabric rises to the right and descends to form the satin because the elastic yarn is positioned below the upward and downward sinker loops constituting the satin. On the other hand, in the elastic warp knitted fabric of the present invention, since the sinker loop in one direction is sunk downward by the elastic yarn, only the other sinker loop emerges on the surface of the knitted fabric, and is usually A beautiful woven appearance with a different weft effect from the elastic warp knit satin gives a fresh impression to the viewer.

[0015]

The present invention will be described in more detail with reference to the following examples. Example 1, Comparative Example 1 The yarn, knitting machine and knitting structure used were as shown in Table 1,
An elastic warp knitted fabric having the structure shown in FIG. 1 and having the finishing characteristics shown in Table 1 was produced. In the finishing characteristics, the elongation is a value obtained by measuring the elongation of the knitted fabric when the knitted fabric is cut into a width of 5 cm and a load of 1.5 kg is applied in the length direction, in%. The elastic warp knitted fabric obtained in Example 1 exhibited a woven appearance with a weft effect, whereas the elastic warp knitted fabric of Comparative Example 1 (conventional method) exhibited a normal warp knitted satin appearance. There was only.
